Zawia Desalination Plant Project

Zawia Desalination Plant Project

Zawia Desalination Plant Project, located in Zawia city in western part of Libya in 60 km distance to capital city Tripoli, was in part of a development plan implemented by General Electricity Company of Libya, in the period of 40th Anniversary preparations of Libyan Leader, to cover high demand of reliable water sources in eastern part of Libya.

The Project consisted of engineering, procurement, construction, commissioning and start-up of a 4×20.000 m3/day Water Production Plant with three type of fuel, Heavy Fuel Oil (HFO), NG and Light Fuel Oil (LFO), complete with all Balance of Plant (BOP) systems. NG is planned to be used as main fuel for MED Desalination Plant operation whereas; heavy fuel oil (HFO) are used as back-up fuels.

Main process and equipment, MED evaporators, boilers and auxiliaries are supplied by Sidem (Veolia, FR) as consortium partner of the Project.

The project includes a relatively large water distribution network line in 142 km with water storage tanks and pumping stations.

Zawia, Libya

Zawia Desalination Plant is expected to address the growing demand for water in western part of the country and supply reliable water to public.

Project site is located in Zawia city in the western part of Libya in a highly populated area. ENKA, while executing the work, successfully managed cultural relations with locals to avoid any clashes and maintained good relations with its neighbors.

Soil improvement has to be performed by means of replacement of subsoil with adequate fill material in the project site for foundations of heavy loads.

Such regional location and high temperatures during summer months created unique challenges for the project workforce peaked at 620 employees.


ENKA has self-performed the basic engineering, detail engineering, procurement, construction, commissioning, start-up and performance testing scope for the project utilizing in-house resources on a lump sum turn-key basis. Specific scope of services provided by ENKA included; complete basic and detailed design and engineering of the plant, supply of all balance of plant (BOP) systems and equipment, all civil works including foundations and structural steel, Product Water Tanks (2×20,000 m3), Make Up Water Tank (1×500 m3), LFO Tank (1×2,500 m3), complete interconnecting piping of the plant, firefighting system, MV/LV electrical & control and switchgear systems with aux. transformers, instrument and plant air supply systems, Emergency Diesel Generators, waste collection and treatment system, batteries and UPS System, ventilation and air conditioning (HVAC) systems, overhead cranes and maintenance hoists, power plant distributed control system (DCS), mechanical and electrical erection, complete civil and structural works, supply of spare parts, and start-up and commissioning of the plant. ENKA further provided training for the O&M personnel who will be operating and maintaining the plant.

ENKA scope also covers 142.000 m water distribution DI piping line with 9 pcs of water storage tanks (2×20,000 m³, 5×10,000 m3, 1×5,000 m3, 1×2,500 m3) and 4 pcs of pumping stations.

  • 2.5 million man-hours
  • The largest capacity of Desalination Plant Project in Libya
